According to the Cyber Security Breaches Survey 2025/2026, 43% of UK businesses experienced a cyber attack within 12 months.
While hackers target UK businesses of all sizes, small ones are often viewed as easy targets. Perpetrators understand that many small businesses lack the funds for strong cybersecurity measures.
But understanding the common threats and network entry points will help you shield your business against attacks.
The Most Common Entry Points for Cybersecurity Breaches
Cybersecurity attacks only succeed if perpetrators find a vulnerability to exploit. To stay safe, watch out for common entry points.
Weak Passwords
Hackers often use automatic tools to test countless password combinations in brute-force attacks. Tools may crack a weak password within minutes, if not seconds.
Outdated Software
Outdated operating systems and other software may carry well-known security vulnerabilities. The more outdated software is, the easier it is for hackers to use as a network entry point.
Phishing Messages
Phishing scammers usually pose as financial institutions or industry authority figures to appear credible. Employees without cybersecurity training may click links to download infected attachments or software.
Human Error
Employees may accidentally send access details or business-critical information to the wrong recipients. Untrained individuals may also misconfigure software settings and inadvertently create entry points.
Warning Signs that Your Small Business is Unprepared for a Cybersecurity Breach
Cybersecurity breach statistics reveal that an attack occurred every 14 minutes in 2025. How do you know if your small business is unprepared for a breach? There are several common warning signs – and according to NordVPN’s research, many small businesses only discover these gaps after a breach has already occurred.
You Have No Password Policy
Small businesses without a password policy risk cybersecurity breaches. Employees may use the same password for multiple accounts in the workplace. Additionally, workers might never update passwords or share them with colleagues.
You Ignore Software Updates
Ignoring software updates can be dangerous, as outdated software is more vulnerable to breaches. You may find frequent notifications about updates frustrating while working, but never overlook them.
Your Staff Have No Cybersecurity Training
A lack of cybersecurity training can cause employees to make avoidable mistakes. They may inadvertently create entry points for hackers to penetrate your network and steal critical information.
Your Employees Use Personal Devices for Work
Employees should never use their own laptops or phones for work. Accessing work files can create safety flaws, as employees may lack effective security software. If their device is hacked, your data will be at risk.
How to Protect Your Small Business Against Cybersecurity Breaches
Creating and executing an effective cybersecurity plan for your small business may seem daunting. To make it easier, take one impactful action at a time.
Build a Cybersecurity Strategy
A good cybersecurity strategy will help you put safeguards into place and handle potential breaches.
The National Security Cyber Centre provides a free Cyber Action Toolkit to help small businesses stay safe. Answer a series of questions to receive customised directions and advice.
Invest in Employee Cybersecurity Training
Organise employee training to reduce security mistakes and minimise entry points.
Finding room in your budget for cybersecurity training may be difficult. However, the fallout of a cybersecurity breach is often costly, too. Investing in training today could save much more money tomorrow.
Integrate Trusted Security Software into Your Infrastructure
Use premium security software (such as leading firewalls and antivirus programs) to prevent unauthorised access. If you or remote employees rely on public Wi-Fi, set up a virtual private network (VPN) to encrypt data, too.
Use Data Backup for Disaster Recovery
Backing up data to the cloud ensures that you and your team can continue to work after a cybersecurity breach. You’ll be able to access essential files from uninfected devices on secured networks.
Keep Software Updated
Update all software to access the latest security patches and features. Set up automatic updates and make sure that staff never dismiss notifications while working.
Protecting Your Small Business Against Cybersecurity Breaches
Hackers employ more varied and powerful methods than ever to breach business networks. But as a business leader, you can take a stand against attackers and their sophisticated techniques.
Build a solid plan for your team. Break down how to identify and handle cybersecurity threats in an organised way. Train your employees to recognise suspicious activity and report it to the right person.
Over time, you can prevent cybersecurity breaches and keep hackers out of your network.
